It started when I wanted to export my bookmarks to html. it would crash. now it crashes if I ask for options. Something changed my homepage and when I went to my preferred homepage and attempted to copy the address it crashed. I seem to be able to browse OK. My bookmarks seem to be intact and I can click on different site. but if I try and do anything like do something with my bookmarks or choose options it crashes. I started with 54.01 64 bit and downloaded 55 but it still crashes. My operating system is Windows 7. All my other programs and various browsers are working fine.

I think that this file cmdshim64.dll is part of your COMODO security software, so there is probably nothing to worry about.

You can check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
